A term in which college age students use to describe being exiled from their dorm or apartment when one of the roommates is engaging in sexual activity. This usually happens because the occupant does not want to be interrupted. A way in which to notify the roommate would be to hang a "You've Been Sexiled" hanger on the outside door handle of the residency. These hang tags can be found and downloaded for free at www.thesexiled.com

Julian just got sexiled by his roommate Joe, because Joe was having sex with multiple blow up dolls and/or Julian's girlfriend. Sorry dude, but you just got "Sexiled"

The past-participle of the verb sexile.
To be banished from one's room (most often, a single-space dormitory room) so that the roommate may engage in private sexual intercourse. Generally speaking, sodomy, cunninglingus, fellatio, and most forms of foreplay consitute grounds for sexiling.

"Last night my roomate brought back some grotsky ho and I was sexiled to the student lounge."

To be "exiled" or banished from the dorm while it is being used by a roommate wanting privacy for (often overnight) sexual activity.
It is a common phenomenon at college, often done willingly by arrangement, which may include telltale signs to show the room is being used (i.e. a strategically placed sock or tie). Where sexiling becomes too regular and inconsiderate, the solution is another Urban Dictionary favourite = Cockblocking.

I was sexiled last night when Brad wanted to take a girl back to our room to stay the night.
